Answer:

s = 35 degrees

Step-by-step explanation:

A triangle has to have a total of 180 degrees.

Step 1: add known angles

114+ 31 = 145

Step 2: subtract sum from 180

180 - 145 = 35

s = 35 degrees

What is the sum (2/5 x +5/8)+(1/5 x - 1/4)?

Artyom0805 [142]

$\left(\dfrac{2}{5}x+\dfrac{5}{8}\right)+\left(\dfrac{1}{5}x-\dfrac{1}{4}\right)=\left(\dfrac{2}{5}x+\dfrac{1}{5}x\right)+\left(\dfrac{5}{8}-\dfrac{1}{4}\right)\\\\=\dfrac{2+1}{5}x+\left(\dfrac{5}{8}-\dfrac{1\cdot2}{4\cdot2}\right)=\dfrac{3}{5}x+\left(\dfrac{5}{8}-\dfrac{2}{8}\right)\\\\=\dfrac{3}{5}x+\dfrac{5-2}{8}=\boxed{\dfrac{3}{5}x+\dfrac{3}{8}}$
